Title: Improvements in valves for Fluids
IPC: F02P5/10
Filed: 1966-10-17
Abstract: 1,161,344. Fluid pressure control valves. F. & E. MFG. CO. 17 Oct., 1966 [18 Oct., 1965], No.46260/66. Heading F2V. [Also in Division F1] A valve assembly, for use in conjunction with the distributer of a car engine and designed to advance the spark during deceleration, so minimizing hydrocarbon formation, comprises a housing 10, having therein two chambers 11 and 12 interconnected by a duct 40, a shaft 32, havconnected to one of its ends a flexible diaghragm 26 and to the other a valve closure member 43, and a passage 14 extending from chamber 11 and two passages 16 and 23 extending from chamber 12. The diaphragm housing is open on one side, so subjecting the diaphragm to atmosphere pressure, this being counteracted by a spring 36. The valve closure member is swivelly mounted on the shaft, so as to ensure proper sealing between its face 44 and a gasket 42, and has on its opposite face a resilient washer 51, for co-operation with a secondary valve seat 50. In operation, spring 36 retains the closure member in the position shown, but upon certain decelerations the manifold vacuum connected to passage 14, increases sufficiently to move the closure member 43 from its seat 41 and against the seat 52, thereby bringing the manifold vacuum into communication with the vacuum element of ignition distributer connected to passageway 16.

Filed: 1969-09-24
Abstract: 1275799 Riveting WARREN FASTENER CORP 24 Sept 1969 [25 Sept 1968 31 Dec 1968] 46916/69 Heading B3U [Also in Division F2] In a method of securing an apertured article 24 to a metal support 22, a tubular rivet 26 is welded to the support without piercing the latter and the article 24 is positioned to abut the support with the rivet 26 projecting through the hole 28 in the article, the projecting end portion of the rivet being deformed radially to hold the article 24 against the support. The riveting action is performed by a gun 120 having a centring plunger 176 spring urged to project from a tubular anvil 164 for engagement in the tubular body of the rivet. A compression spring 174 urges the anvil 164 outwardly of the gun. Admission of compressed air into a cylinder 134 of the gun moves a piston 136 leftwards (Fig. 10) so that its piston rod 154 strikes the rear of the anvil 164 to cause the riveting action. Air trapped between two lands of different diameter at the ends of the piston 136 is compressed as the piston moves leftwards in the stepped cylinder bore and acts to return the piston to its initial position when the pressure supply is cut off.

These members (15 in Fig. 4, not shown) are operated by hydraulic cylinders 23. The hydraulic separate means comprises cylinders 50 mounted on a plate 48 secured to the projecting portion 46 of the piston 10, and pistons 52 adapted to bear against the crosshead 14. Ejector means (not shown) within the mould M1 is operated by a double-acting piston 55 and rod 56.

Title: Apparatus for cleaning textile fibrous material
IPC: D01G9/06
Filed: 1962-12-14
Abstract: 963,053. Cleaning fibrous materials. W. A. LATOUR Dec. 14, 1962 [Jan. 15, 1962] , No. 47339/62. Heading D1N. Apparatus for cleaning fibres includes a rotatable feed roll provided with a plurality of rows of two-pointed teeth in axial rows. The feed roll is stated to be non-loading and optimum tooth density is given as 75 to 90 points to the square inch with teeth in the direction of the axis at about 15 points per linear inch. Rows of teeth 15 are staggered and are spaced about # inch apart, spacing between teeth being about 3/64 inch with a tooth height of about # inch. Fibres are received by the feed roll 12 from coacting feed rolls 11, 11a which may be smooth or have roughened surfaces. A combing roll 13 coacts with feed roll 12 to loosen tufts and arrange fibres parallel to one another. This roll 13 is covered with saw-tooth wire and rotates at about one fourth of the peripheral speed of roll 12. From roll 12 the fibres are transferred to a cylinder 14 arranged to rotate with a peripheral speed about 100 to 150 times that of roll 12. Associated with the cylinder 14 are bars 18 against which fibres are buffeted to remove most of the impurities. Attached to the bars 18 are baffles 19 that cause fibres separated from trash to be returned to the teeth of the cylinder 14 from which partially cleaned fibres are doffed on to a suction cage condenser 25 by air currents directed against the cylinder at an angle of 45 degrees. A roll 29 clothed in similar manner to the roll 12 removes the fibres from the condenser 25 and returns them to cylinder 14 for further cleaning, this time in conjunction with bars 51. Again air currents are employed to doff the cylinder 14 and the fibres are collected on a screen 42. In a modified form, air drawn through the condenser 25 is not passed into chamber 34 but into chamber 37.

Title: Horizontal deflection circuit arrangements for cathode ray tubes
IPC: H04N3/223
Filed: 1975-11-20
Abstract: 1525497 Horizontal deflection circuit for television SONY CORP 20 Nov 1975 [29 Nov 1974] 47839/75 Heading H3T A cathode-ray tube horizontal deflection circuit comprises a switch device, such as transistor 3 arranged to swiitch current into and out of deflection coil 6 and a variable impedance such as saturable reactor 10 connected in series with the deflection coil 6 and controlled in response to changes in voltage across the switching device 3 so as to keep the deflection current constant. The invention is applicable to a television receiver and avoids change in raster size when the speed of e.g. a video tape recording and/or reproduction apparatus changes. Flyback pulses derived from the secondary 8b of transformer 8 are rectified at 12 and produce a D.C. voltage e.g. 18V at 26 which is inversely proportional to the frequency of the horizontal drive fed to terminal 2. This voltage is compared with a reference by transistors 15 and 16 and the resulting error used to control the current in transistor 25 and hence to control the inductance of saturable reactor 10 so as to tend to keep constant the line deflection current in coil 6. A parabolic field waveform may be applied from circuit 27 so as to correct pincushion distortion.

The first array preferably composes a conductive grid coated with a photo-conductor, optionally together with an insulator, the pattern being formed by imagewise exposure, optionally after uniform charging. The two arrays may be integrally combined by insulating spacers. In embodiments, two conductive arrays, and/or two first arrays are used, in the latter case, an array in the form of photoconductive grid is used to modulate the flow of ions on to an insulating array to form thereon a charge iamge which is then used to form charge images on one or more receptor sheets.

Abstract: 1,179,933. Electrolytic recording sheets. PHOTOCIRCUITS CORP. 25 Oct., 1967 [27 Oct., 1966], No. 48552/67. Heading D2B. [Also in Division G1] A multilayer printed circuit board is tested for continuity and short circuits by placing it together with a recipient sheet 39 and source sheet 40, which are suitably impregnated so that electrophoretic transfer of charged particles will occur when potential is applied across them, between conductive plates 1 and 4. Potential is applied between the plates 1 and 4 and a coloured pattern appears in the recipient sheet indicating those terminals at the lower face c of the board which have attained the potential of the plate 1. This pattern may then be compared with a reference pattern. To test for continuity or short circuits between particular terminals on the top and bottom faces of the board, templates 52 of insulating material with holes corresponding to the terminals to be tested are inserted adjacent the top face of the board. Contacts are established through the holes via flexible graphite pads 51. A further template at the bottom may be introduced, e.g. to select terminals which should be insulated from the top face terminal, and observation made as to whether any marking appears on the recipient sheet. The sheets are densely packed filter papers with their fibres perpendicular to the surface and are impregnated with water or a weak electrolyte solution of any inorganic acid salt e.g. potassium nitrate, sodium chloride, potassium sulphate. The source sheet is also impregnated with a colour dye whose particles when charged will migrate to the recipient sheeta list of suitable dyes is given in the specification. Alternatively chemicals may be contained in the source and recipient sheets which react on contact to produce a noticeable colour change. Suitable combinations might be betaresorcylic acid on one sheet and ferrobromosulphite on the other or ammonium salt of nitrophenyl hydroxylamine on one and phenyl hydrozine or ferric sulphite on the other. The recipient and source sheets may in fact be one sheet, initially charged on one side only.
